1 Claim.

Still another object of the invention is to provide a universal stave which may be employed in the construction of silos or tanks of various diameters.

Referring to the drawing in detail;

Figure 1 is a plan view of a mold constructed in accordance with the invention.

Figure 2 is a side elevational view thereof.

Figure 3 is a sectional View taken on line 33, of Figure 2.

Figure 4 is a sectional view taken on line 44 of Figure 1.

Figure 5 is a sectional view taken on line 55 of Figure 1.

Figure 6 is a segmental perspective view illustrating the manner of connecting the side bars with the end plates of the mold.

Referring to the drawing in detail, the mold, which is substantially rectangular in formation, embodies a pallet 5, which is formed with offset portions 6 and 1, extending throughout the entire length of the mold, the offset portionsbeing disposed at the edges of the pallet.

The reference character 8 designates the side bar at one side of the mold, and the reference character 9 indicates the side bar at the opposite side of the mold. The side bar 8 is formed with an inwardly extended rib l0 disposed intermediate the upper and lower edges thereof, the rib I 0 extending inwardly an appreciable distance beyond the normal inner edges of the side bar 8, as clearly shown by Figure 3 of the drawing. As shown, the surfaces of the rib ID are inclined, and curved at the bottoms, so that the stave formed by the mold will be provided with a groove along one of its side edges, the outer ends of the groove bein curved.

The side bar 9 is somewhat different in construction, and includes a central longitudinal rib 2 I I, the upper and lower surfaces thereof being also inclined. The portions of the side bar 9 between the edges thereof and the inner end of the rib II are curved outwardly as at l2, or in a direction opposite to the curvature of the bottoms of the inclined surfaces of the rib l9. Due to this construction, the edge of the stave with which the side bar 9 contacts will be formed with a curved groove or socket extending throughout the length of the side bar 9.

Formed at the ends of each side bar is an ear l3, which is formed with an elongated opening 14, the ears of the side bars being shaped to fit within the elongated openings l5 of the end plate iii of the mold. These end plates [6 close the ends of the mold and rest squarely against the ends of the pallet.

When assembling the mold, the ears l3, after they have been extended through the openings l5, are secured in position by means of keys H, which are beveled, so that when they are driven into the openings [4 a binding action will be set up between the key, side bars and end plates and the' elements of the mold will be securely held together, but may be readily removed or stripped from the stave molded thereby.

The openings are formed in the side bars 8 and 9, and are disposed in spaced relation with respect to each other for the reception of reinforcing rods which have become imbedded in the material poured into the mold.

After the material poured into the mold has set for a predetermined period of time, the keys ll are driven from the openings M. The end bars may now be removed, and the stave moulded maybe lifted with its pallet to a place where the moulded stave may be set until it may be removed and placed on a curing stand.

It might be further stated that one of the end plates I6 is formed with a transversely disposed rib l8, while the opposite end plate is formed with a correspondingly shaped groove 19, to the end that the moulded stave will have a groove in one end and a rib at its opposite end.

What is claimed:

In a mold, a pallet constructed of sheet metal material, said pallet having offset portions formed along the longitudinal side edges thereof, providing shoulders, side bars of widths equal to the widths of the offset portions, adapted to 3 4 rest within the offset portions of the pallet, wide extensions having openings, formed at the ends REFERENCES CITED of the side bars the wide face of the extensions The foll i ef n are of record in the being horizontally disposed, wide end plates havfile of this patent; ing openings elongated longitudinally of the end 5 plates, adapted. to receive said extensions, and UNITED STATES PATENTS tapered rectangular keys adapted to be driven Number Name Date into the openings of the extensions, the keys oon- 1136554 Crisenberry June 13, 1916 tactingwith the end plates and adapted to draw 1,175,011 Phmipofi, Man 14 1916 the side bars into close engagement with the lon- 10 1,102,360 Ives 19, 1911 gitudinal shoulders of the pallet.
